Abstract

A streaking pin, having an elongated body portion, with the lower end having a hook for hooking strands of hair during the streaking process. The body portion of the pin would be housed within an elongated housing, the housing having a pair of spring members, accommodating the pin through the coils of the spring, with the lower spring member positioned so as to allow the extending of the lower portion of the pin out of the housing during the pulling of the hair, and with the upper spring member for allowing retraction of the pin partially into the housing should the end of the pin make contact with the scalp or the like. The apparatus would further include a cap member for enclosing the exposed hook portion of the pin when the apparatus is not in use.

Claims

exact text as granted — not AI-modified
What is claimed as invention is: 
     
       1. A hair streaking pin comprising: (a) a pin portion, having a substantially cylindrical elongated body, with a hook portion on a distal end thereof;   (b) a housing having an upper and lower portion, and having an open end on its lower portion, for allowing the hook portion of the pin to extend out from the housing;   (c) first spring means in the lower portion of the housing, for returning the pin to its normal position within the housing after the hook portion of the pin has grasped strands of hair;   (d) second spring means positioned within the upper portion of the housing for returning the pin to its normal position within the housing after the pin has moved inward against the bias of the second spring means when the hook portion has struck a scalp; and   (e) means within the housing for preventing rotation of the pin within the housing during the hair streaking process.   
     
     
       2. The apparatus in claim 1, wherein the housing further includes an upper portion which is removable from the lower portion of the housing. 
     
     
       3. The apparatus in claim 1, wherein the pin member further includes a broadened central body portion along its cylindrical length. 
     
     
       4. The apparatus in claim 1, wherein there is further included a stop in the upper portion of the housing for preventing the hook portion of the pin from moving into the housing when the hook strikes the scalp. 
     
     
       5. The apparatus in claim 1, wherein the means for preventing rotation of the pin within the housing further includes a plurality of tab members positioned around an interior surface of a wall of the housing, at the lower portion so that as the pin attempts to rotate within the housing it is obstructed in its rotation by the plurality of tab members. 
     
     
       6. A streaking pin and housing composite apparatus, comprising: (a) a substantially cylindrical pin member, having a central flared body portion, and a hook on a distal end for grasping strands of hair during streaking;   (b) a housing having a central bore therethrough, the housing further comprising: (i) a lower portion, having a bore therethrough and a port at its distal end for receiving a lower end of the pin, so that the hook extends out of the bore of the housing;   (ii) a first spring member, positioned between the flared body portion of the pin and the lower end of the housing, so that as the pin moves downward through the bore of the housing against the bias of the first spring member, the first spring member will return the pin to its normal position within the lower portion of the housing;   (iii) an upper portion of the housing, further including a second spring member, positioned between an upper end of the pin and the body portion, the second spring member returning the pin to its normal position after the pin has struck a surface and retracts within the housing; and     (c) means within the upper portion of the housing for preventing the pin from retracting fully into the housing.   
     
     
       7. The apparatus in claim 6, further comprising a stop in the upper housing to prevent the pin from retracting fully into the housing. 
     
     
       8. The apparatus in claim 6, wherein the housing is removable into upper and lower portions. 
     
     
       9. The apparatus in claim 6, further comprising means to prevent the pin from rotating within the housing. 
     
     
       10. The apparatus in claim 9, wherein said means to prevent rotating of the pin comprises a stop at a level of the flared body portion of the pin member.
